The last question I have is on slide 22. You talk about the potential energy savings in each of the categories. In residential, there are savings of up to 27% by 2025, industrial savings of 14% by 2025, and commercial savings of 23% by 2025. With respect to each of these categories, are you assuming those to be steady-state savings, or front-end-loaded savings, or are you assuming we'll achieve those more towards the 2025 timeframe? That means something completely different to me, depending on what your assumptions are.
